Glossary
Short definitions for the casino and betting terms we use when comparing licensed UK operators.
Comparison sites throw around jargon quickly. This glossary explains the words that actually affect how you read our scores — especially around slots, live casino and welcome offers.
RNG
Random Number Generator — software that determines slot and digital table outcomes. UK-licensed games use tested RNGs audited by approved testing houses.
RTP
Return to Player — the theoretical percentage a game pays back over millions of spins. A 96% RTP slot returns £96 per £100 wagered on average, though individual sessions vary widely.
Volatility
How often and how large a slot pays. Low volatility means frequent small wins; high volatility means longer dry spells with bigger potential hits.
Wagering requirement
The number of times you must bet bonus funds before withdrawing. A 35x requirement on a £50 bonus means £1,750 in total bets before cashing out bonus-derived winnings.
Live dealer
Real-time casino games streamed from a studio with human croupiers. You place bets digitally while watching the physical table via video feed.
UKGC
UK Gambling Commission — the regulator issuing licences to online gambling operators serving customers in Great Britain.
GamStop
A free UK self-exclusion scheme covering licensed online gambling operators. Once registered, participating sites must block your account for the chosen period.
Paylines
The patterns across slot reels that trigger a win when matching symbols land. Modern slots may use hundreds of ways-to-win instead of fixed lines.
Game show live games
Live-dealer titles based on TV-style formats — wheel spins, prize ladders and bonus rounds hosted by a presenter rather than traditional card or table play.
Self-exclusion
A tool letting you block yourself from gambling for a set period, either through an individual operator or via GamStop across the UK market.
